Abstract

A actuating device for a vehicle, especially an automobile, in which an actuating device such as a hydraulic brake master cylinder and booster, is arranged to extend within an engine room at an angle to the longitudinal direction of the automobile body to fit in a restricted space and has its rear end portion protruding into the operator compartment. A pedal arm is supported on the rear end portion of said actuator by a hinge pin arranged in a plane substantially normal to the center line of the actuator, but is inclined with respect to a horizontal plane such that the moving locus of the foot pedal at the rear end of the pedal arm generally follows a longitudinal vertical plane to provide a normal motion for the operator's foot during movement.

Description

The present invention relates to a actuating device for an automobile and, more particularly, to a actuating device of the type in which an actuator arranged to extend within an engine room in the longitudinal direction of a vehicle, such as a car, body and to have its rear end portion protruding into a compartment is fastened to the dash board of the vehicle body and in which a pedal arm is supported on the rear end portion of the actuator through a hinge pin arranged in a plane substantially normal to the center line of the actuator.

For actuators that are very long or if the space in the engine room is restricted or narrow, there arises a problem that the actuator and the engine or its accessories interfere with each other.

It is an object of the present invention to provide a simple and effective actuating device in which, even if the longitudinal center line of said actuator is inclined with respect to a vertical plane containing the longitudinal center line of the vehicle body as to obviate the aforementioned interference and the movement of the pedal is not offset transversely of the vehicle body whereby the driver's feeling is substantially similar to the prior art having the actuator longitudinally aligned with vehicle.

The present invention will be described in the following in connection with one embodiment thereof with reference to the accompanying drawings.

FIG. 1 is a top plan view showing a portion of an automobile which is equipped with a pedal actuating device according to one embodiment of the present invention.

FIG. 2 is a longitudinal sectional side elevation of the automobile of FIG. 1.

FIG. 3 is an enlarged view showing an essential portion of FIG. 1.

FIG. 4 is a view taken in the direction of arrow IV of FIG. 3.

FIG. 5 is a view showing the moving loci of the pedal in different arrangements for comparison.

As shown in FIGS. 1 and 2, a car body B is formed at its front portion with an engine room R1 and at its rear portion with a compartment R2, which are partitioned by a dash board 1 forming a part of the car body B. In the engine room R1, there are respectively arranged an engine 2 at a central portion, a pair of spring and shock absorber housings 3 and 3' at both right and left corners adjoining the dash board 1, and an actuator 4 for use with the pedal actuating device according to the present invention adjacent to the righthand rear portion of the engine 2.

The actuator 4 is constructed of a tandem type brake master cylinder 5, a vacuum booster 6 joined to the rear end portion of the master cylinder 5, and a pedal bracket 7 fastened to the rear end portion of the booster 6 by means of bolts 8. The actuator 4 is mounted on the dash board 1 such that the dash board 1 is sandwiched between the booster 6 and the pedal bracket 7. As a result, there is arranged in the compartment R2 the pedal bracket 7 on which a pedal arm 9 is supported through a hinge pin 10. The pedal arm 9 actuates the booster 6, when it is pivoted forward on the hinge pin by depressing its foot pedal 9a, to boost the brake master cylinder 5 so that the not-shown wheel brakes can be actuated.

As clearly seen from FIG. 3, the total length of the brake master cylinder and the booster 6 is larger than the spacing between the engine 2 and the dash board 1. In order to position the front end portion of the brake master cylinder 5 between the engine 2 and the righthand housing 3', the actuator 4 is arranged such that its longitudinal center line O1 is inclined at an angle θ1 with respect to a vertical plane V1 containing the longitudinal center line of the car body B. Because of this inclined arrangement, in the shown embodiment, the wall la of the dash board 1 for mounting the booster 6 is recessed at an inclination into the compartment R2.

Moreover, the aforementioned hinge pin 10 is arranged such that its center line O2 is generally contained in a plane normal to the center line O1 of the actuator 4, i.e., a normal plane V2, of the center line O1 and inclined at an angle θ2 rightwardly downward of the car body B with respect to a horizontal plane H (as shown in FIG. 4).

The positioning of the center line O2 of the hinge pin 10 in the plane V2 normal to the center line O1 of the actuator 4 is a necessary requirement for transmitting the operating force of the pedal arm 9 to the input lever of the booster 6 without creating difficulty which is well known in the prior art.

With the actuator 4 arranged at an inclination, as has been described hereinbefore, it normally would be assumed that the center line O2 of the hinge 10 should be horizontally arranged, as in the prior art. With such an arrangement the locus L1 of the foot pedal 9a, which follows the turn of the pedal arm 9, as viewed from above, would be inclined at an angle θ with respect to the vertical plane V1 containing the longitudinal center line of the car body B, as shown in FIG. 5. As a result, the foot pedal 9a moves to the right as it is depressed forward, which is an uncomfortable feeling for the driver.

According to the present device, since the center line O2 of the hinge pin 10 is inclined at the angle θ2 rightwardly downward of the car body B with respect to the horizontal plane H, the rightward offset of the aforementioned locus L1 of the pedal 9a is corrected by that inclination so that the pedal 9a draws a slightly curved locus L2 that generally follows the vertical plane V1 containing the longitudinal center line of the car body B.

As has been described hereinbefore, according to the present device, the longitudinal center line of the actuator is inclined with respect to the vertical plane containing the longitudinal center line of the car body. As a result, even if the actuator is elongated or if the engine room is narrowed, the interference between the actuator and the engine or its accessories can be obviated. Moreover, the center line of the hinge pin of the pedal arm is inclined with respect to the horizontal plane so that the moving locus of the pedal at the rear end of the pedal arm may generally follow the vertical plane containing the longitudinal center line of the car body. As a result, despite the inclined arrangement of the actuator, the pedal can draw the moving locus substantially identical to that of the prior art while making the driver feel no sense of incompatibility. Furthermore, the construction is no more complicated than the prior art.
